Functions

func CheckResponse 

func CheckResponse(r *http.Response) error

CheckResponse checks the API response for errors, and returns them if present. A response is considered an error if it has a status code outside the 200 range.

func EscapeForFilter 

func EscapeForFilter(s string) string

EscapeForFilter escapes an abitrary string for use as a filter query parameter.

Special characters that are part of the query syntax will be escaped. The list of special characters are:

+ - & | ! ( ) { } [ ] ^ ' " ~ * ? : \

Additionally, space will be escaped. Characters are escaped by using \ before the character.
